Referring to the accompanying drawings, 2 1 designates 'a conventionalrepresentation of a flushing tank which has the usual, or any preferredtype of float valveconnnunication with a source of watersupply. baidtank is divided horizontally by means of a diaphragm'2 to form anupperc'hamber :or compartment 3 in which the float valve communicationwith the source of watersupply is mounted, and a lower com artment 4. Anopening 5 formed in the diaphragm 2 is provided with a valve seat- 6,said opening forming the communication between the upper chamber 3 andthe lower chamber 41- :and? is controlled by means ofa valve 7 having astem 7 a which projects through and is 5 guided by a gland extension 8carried by the 1 valve seat 6. I The lower chamber or room- 3partment-C. has an 'op'enin'gt) ,formed through its bottom whichreceives a bushing 10 prov-ided with exterior threadsll which are on ESpecification of Letters Patent.

! an interiorly threaded end 12 of a valve chamber 13 having a valveseat 1-1. 'ztorm'ed in its upper portion. The stem 7 oif the valve 57extends through the lower chamber 4 and into and below the valve seat14in the valve chamber 13 and carries a valve p A short pipe section 16has its upper end i held in engagement with the bottom of the valvechamber 13 by means of a detachable coupling '17, said pipe having itslower end nested within another pipe section 18 the lower end of whichis provided with a longitudinal slot 1 9 and held within an enlargedcoupling head 20 of the pipe 21 that delivers the flushing water to thecloset bowl. The

coupling head 20 is of considerably larger diameter than the pipesection 18, and at one side has a bulged out portion 22 which is open tothe atmosphere.

The stem or rod 7 a is fast within the valve 15 and projects beyond thesame, and its projected end carri'esn threadedcoupling 23 which holds inengagement therewith a valve 3 operating rod 24 that extends through thetwo pipe sections 17 and 18 and has its lower end portion upturned asindicated at 2'5, and projected through the slotted end of the pipesection 18 and up through the bulged portion-of the coupling head 20.The end of the upturned portion 25 is threaded for the reception of-alock nut 26 which re tainsian eye 27 thereon'from which projects avertically arranged pivot ear 28 which has a pivotal connection with avertically arranged *rod 29 the lower end of which carries a pivot earfor pivotal connection one to end of a rocker arm '30. Said rocker arm30 has its outer portion bifurcated to form two spaced apart strapmembers 3132 which have pivot openings 33 formed through them forengagement with a hinge connection '34- carried {by the water closetseat framing The ends of said strap members 31 and 32 carry ears 36which receive pintles 37 of hinge members 38 carried bythewatercloset'seat 39. The seat cover 40 has "the usual hinge connection41 with the dlosetlseat 39.

In Fig. 1 of the accompanying drawings the closet :seat and valveconnection with thesource of water supply is shown in the positions theyassume when the closet is not in use. In this position the weight of thewater in the upper compartment 3 of thereby depressing the rod 24,moving the valve 15 from its seat 14, and causing the rocker arm to holdthe closet seat raised from its framing. It will be seen that when theseat is occupied, the rocker arm exerts an upward pressure on the rod 24sufficient to push the valve 15 to its seat 14, and through theconnection between said valve 15 and the valve 7 raise the latter valvefrom its seat and thereby permit the water from the upper compartment toescape into the lower compartment 4 and the valve chamber 13 filling thesame, but be retained therein owing to the valve chamber being closedthrough the seating of the valve 15. WVhe-n the weight is removed fromthe seat, the pressure of the incoming water in the upper compartment 3will force the valve 7 to its seat, thereby cutting ofi the supply ofwater to the lower compartment 4, and remove the valve 15 from its seat14, to allow the water that has accumulated in the said compartment 4and valve chamber 13 to flow into and flush the closet bowl;

Any suitable means may be employedfor supplying the necessary air to thelower compartment 4 of the flushing tank, one convenient form beingillustrated in the drawings wherein an upstanding pipe 42 carried by thediaphragm 2 communicates with the air above the upper compartment 3 anddelivers the air through an opening 43 to said lower compartment.

In addition to the automatically acting features of the valves, it willbe seen that the present system is one that is so arranged that thevarious connections thereof may be readily disconnected to permit of theoperating mechanism being readily inspected or repaired, or replaced,should the same be necessary or desirable. For instance the valvechamber 13 may be readily disconnected from the bushing carried by thetank; the pipe section 16, through its coupling connection 17 may bereadily disconnected from the valve chamber to permit inspection orrepair of the valve 7 or the coupling be- 7 tween the valvestem and therod 24; and

the connections between the pipes may be readily disconnected. Also, theconnections between the rocker arm and the seat, and

the connections between the valve operating rod 24 and said rocker arm,is one that may be readily disconnected. Claims 1.
